Please resolve this urgently

Our telkom line has been down since the 24th of April, after holding on for more than an hour at a time just to be cut off a query was finally lodged, it is the 16 of may and we still dont have a telkom line and that means we can use our wifi either, we are paying for a service that we are not even receiving? Every month for at least 2 weeks we either dont have a telephone line or our wifi is down. Should we still be paying for a service we are not receiving or fully receiving? please resolve this issue as it is extremely frustrating.
